It was a quieter start to the day in a swelteringly hot FP1, where the mercury signalled temperatures approaching 40 degrees Celsius - uncharacteristically hot, even for the desert climes of Bahrain. Lewis and Valtteri ended the first session in P10 and P14 after early runs on the Soft tyres but were satisfied with their early work.
"Today overall went well," said Valtteri. "Obviously, it's difficult to learn much in FP1 with the extremely high temperatures, as the main sessions are under the lights in the evening when it's much cooler. But we got some good data out of FP2 with short runs and long runs. The car was feeling good. We can definitely make it better but it was a positive start and I'm looking forward to qualifying.
"It was very hot today and the track normally improves quite a lot as you lose some of the sand, so I'm sure tomorrow we will go a lot quicker. How quick, we will find out. It's definitely tougher than before, driving in the heat with these new cars. But I'm used to being in a Finnish sauna, so it's no problem!
"It seems like the same trend continues here with it being so close with Ferrari. But Red Bull are looking good too and the whole pack is pretty close, if you look at the top six particularly. It looks like every little thing that we are going to be fine tuning today with the setup and anything extra we can find is going to be crucial for qualifying and the race."
